Vector Fixed-Point Multiply and Add Rounded
The products of fixed-point elements in b
(four signed 32-bit integer numbers)
by fixed-point elements in vector c
(four signed 32-bit integer numbers)
are added to the fixed-point elements in vector a
(four signed 32-bit integer numbers).
The multiplication result is not saturated, i.e. exact (-1) * (-1) = 1 is added to the destination.
The rounded and saturated fixed-point results are stored to vector a
.
